To aZZ whom it may concern:

Be it known that I Lome a citizen of the United States, and a resldent of the Acity of Chicago, county. of Cook,

and State of Illinois, have invented certain new -and useful Improvements in Lawn Sprinklers- 4of which the following is a specification. n

My invention relates' to improvements 1n lawn sprinklers, and has for.. its object-the production of a device of this character which willbe automatic in operation and which will be hi hly ecient in use. A

further object is t e production of a sprin.

kler, which, during the seasons of non-use,

will be adapted to drain itself to prevent corrosion such `as otherwise results when permitted to accumureference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is a central vertical sectlon of a sprinkler embodying the invention,H

and

Fig 3 a section-taken on substantially line 3-3of Fig. 2. 'p

The preferred form of construction as illustrated in the drawings comprises a tubular yhousing 5 at the 'lower end of which is provided a T coupling 6, which affords connection with a water sup-ply pipe 7. The vupper end of housing 5 is formed into a cup 8, said'housing being adapted, `when the -device is in use, to be buried in the ground lso that the upper edge of cup -8 is substan-- tially ilush .with the surface of thei ground.

Arranged in the upperv end of said housingtfor free vertical androtary movement therein is ya tubular stem 9. ,Fixedto the upper end of stein 9 is'a nozzle or spraying device consisting of a aring or diverging 5t) bottom plate l10 nd a cap 1,1 which -is securedv to the mem r 10 by means of screws 12. i The lower portion of the interior tof the body of theI nozzle or sprayer thus formed, that is, that portion of the interior of the nozzle within the member 10, is di- D.

.desired freedom `of rotation o vided by a plurality of radial partitions 13. Correspondingly the upper portion of the interior of the body of the nozzle, or that within the cap 11, 1s' divided .by a diametrically extending partition 13', the partitions 13 and 13 affording means of lspacing the cap 11 above the member 10, as will'be readily understood.' Within the cap 11 is formed an annular peripheral passage r roove 14 from which lead inclined outward yfopening passages 14 arranged at opposite sides of the nozzle as will be readily understood. Interposed between the partitions 13 and 13 isa perforated plate 15 which constitutes a straineradapted to prevent the passage of'sand, grit or other impurities through the nozzle' where the same might clog the minute lpassages 14.. -The partitions-13 and 13serve .as backing members adapted to offer resistance for the* water in discharging from the nozzle, pre` venting circulation of .the same in the nozzle as will be readily understood.

The stem 9 is rotatably mounted in a bearing member 16,-threaded into the upper end of housing' 5. Vertical Amovement of the" stem 9 is limited by means of stops 17 and 18; the. former of which is carried'by the member ,16, the latter being'mounted'in a circular groove 19, provided at the Alower end "of the steni, 9 between said stem and The top 17 is metallic and the stop 18 is form d of wood, and when the same contact with each other, friction will be small, thus ermitting the the stem and nozzle carried thereby.v v v 1 With the construction set forth, it will be seen that when water is supplied to the device from.the pipe 7, the same will rise in the housing 5 and enter stern`9 whence the same willber discharged into the interior ofthe nozzle carried at the upper end thereof. After passing through the strainer plate 15, the waters/will enter the annu-lar roove` or'passage 14', whence the same wil j be discharged through the .dis-' charge openings 14.' The' force'A of the water passingupwardly through the stem 9 will -cause the latter to be 'automatically elevated until the stop 18 engages with the sto 17, and the force kof thewater discharged rom the dischargepassages will cause rotation -of the nozzle thereby -effecting spraying of the lawn within a wide radius. When the supooV ply of water to the sprinkler is shut off, the nozzle will return by gravity to its initial lowered position where it will be concealed and out of the way.

VProvided in thelower end 'of the housing 5 is a drain opening 20 which in the summer time, or in season, will be closed by a valve- 21 which is adapted to rest loosely over said opening, there being a conical' seat 22 surrounding said opening to insure centering of the valve thereover. The valve 21 is proto permit of removal of the valve 21. With l zo vided with-a stem 23 which projec'tsupwardly into the stem 9, the stem 23 being of such ,length that when said stem 9 is removed the stem 23 will be accessible so as this arrangement it will be seen'that in the winter time, or out of season, when the sprinkler is not in use, the nozzle and stem thereof may be removed through removal of the member 16, whereupon thevalve 21 may be removed so as to permit of any water accumulating in the housing 5 draining to 'avail myselffof such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as -new and desire to secure by Letters Patentfis: i

- 1. Adevice of the class described comprising a vertically disposed tubular housing having an inlet openingfand a drain valve 1n the lower portion thereof; a spraying device in the form of a tube revolubly and Islidably mounted in said housing and provided-.witl1'an upwardly opening groove about its lower end portion; and a ring of wood mounted wlthin said groove and supported thereby, adapted, by 'engagement with a fixed metal portion of the housing, to l limit the upward movement of the tube, substantially asdescribed.

2. A device of the class described comprising a tubular vertically disposed housing, having an inlet opening in the lower portion thereof; a tubular steml mounted 1n said housing -for free rotary and vertical movement; means for limiting vertical movement of said stem; a-nozzle provided at the upper end of said stem; a dra-in opening in the bottom of said housing; and means removably arranged in said housing for closing said opening, substantially as described. p l

3. A device of the'class described comprising a tubular vertically disposed housing, having an inlet opening in the lower ortion thereof; a tubular stem. mounted 1n said housing for free rotary andyertical movement; means for limiting vertical movement of said stem; a nozzle provided at the upper end of said stem; a drain opening in said housing; a valve adapted to rest loosely over said opening to close the same; and an upwardly projecting stem on said valve accessible at the upper end of said housing upon the removal of said tubular stem, substantially as described.l

4. A' device of the class described comprising a tubular vertically disposed housing, having an inlet opening in the lower portion thereof; a tubular 'stem mounted in said housing for free rotary and vertical movement; means for limiting 'vertical movement of said stem; a nozzle provided at the upper end of Ysaid stem; a drain opening in said housing; a valve adapted to rest loosely over said opening to close ythe same; a conical Aseat surrounding said opening adapted to accommoda-te' said valve; and an upwardly pro-l jecting stem on said valve accessible at the upper end of said housing upon the removal .of said tubular stem, substantially as. de-

scribed.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.
